L. Rosenberger

Alfred L. Rosenberger, Ph.D.

Alfred has worked at the Smithsonian Institution's National Zoological Park conducting research on the conservation biology of monkeys, and at the Smithsonian's National Museum of Natural History, as a Digital Curator for electronic educational outreach. Before he was an Associate Professor of Anthropology at the University of Illinois at Chicago. He has developed educational kiosks and websites focusing on the biology of mammals as well as new research methods involving three-dimensional virtual specimens. His scientific research emphasizes the evolutionary history and adaptations of South and Central American monkeys and the origins of anthropoid primates, which is the taxonomic group to which we belong with monkeys and the more conventional apes. He is forever fascinated by the challenge of creating a multi-disciplinary story of primate evolution. He learned early on, while working toward a Ph.D in Biological Anthropology at the City University of New York, that the study of skulls, skeletons and teeth of museum specimens and fossils makes a lot more sense when one also spends time chasing monkeys in the rain forest to learn what the animals actually do.
